What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This lozenge has three active ingredients. Honey is a natural sweetener and humectant that's been used traditionally for sore throats and minor wounds.

Vitamin C is an antioxidant and immune nutrient, essential for collagen formation and infection defense. Lemon peel essential oil is included for flavor and aroma.

The product also contains cane sugar, tapioca syrup, and maltodextrin as inactive ingredients (the base and binding materials that hold the lozenge together).

Does it work?

Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: immune health support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Honey in this product is possibly effective for cold sores, cough, oral sores (oral mucositis), minor burns, and dry eye — based on clinical evidence, though the strength of that evidence is modest. Vitamin C is effective for vitamin C deficiency and possibly effective for anemia related to chronic disease, heart rhythm problems (atrial fibrillation), cataracts, and infections triggered by heavy exercise.

Lemon peel essential oil's effectiveness for the conditions listed — allergies, anxiety, respiratory infections, and high blood pressure — has insufficient reliable evidence in the data we hold.

The evidence, ingredient by ingredient Honey Vitamin C Lemon

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Honey is generally well tolerated in adults and children over 1 year old, though nausea, stomach pain, and vomiting can occur orally. When applied to skin or inhaled nasally, it may cause burning or stinging.

Avoid honey from the Black Sea coast of Turkey, which can contain toxic grayanotoxins linked to heart rhythm problems and dangerously low blood pressure. Honey is likely safe during pregnancy and breastfeeding as a food; talk to your doctor or pharmacist before using it medicinally.

Vitamin C at normal doses is generally well tolerated but can cause abdominal cramps, heartburn, diarrhea, nausea, and vomiting — especially at doses above 2 grams daily. High-dose vitamin C may cause kidney stones in susceptible people.

The safety data advises against high-dose vitamin C in pregnancy; normal dietary amounts and prenatal vitamins are considered likely safe. Lemon in food amounts is well tolerated; heartburn and stomach upset can occur with fresh lemon juice, and one trial found GI disturbances in 37% of people drinking 60 mL twice daily.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Lemon, Honey, Vitamin C.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; cancer treatments.
  • For scale: 828 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your doctor or pharmacist before taking this product if you're on phenytoin (Dilantin), warfarin or other blood thinners, oral contraceptives or hormone replacement therapy, levothyroxine (thyroid medication), chemotherapy drugs, fluphenazine or other antipsychotics, indinavir or other HIV medications, itraconazole (antifungal), or any drugs processed by your liver (CYP3A4 substrates). Honey and vitamin C together affect how your body handles a large group of medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This lozenge may help with cough and sore throat thanks to its honey content, though the evidence is modest. If you take phenytoin, warfarin, thyroid medication, oral contraceptives, hormone therapy, chemotherapy, an HIV drug, an antipsychotic, or an antifungal, you'll want to check your specific medications with your doctor or pharmacist before starting this product — the interactions could affect how well your drugs work.

The honey and vitamin C here are generally well tolerated, but high-dose vitamin C isn't advised in pregnancy without guidance from your provider. Talk it over with your own doctor or pharmacist to make sure it fits your situation.

Each ingredient & the kinds of drugs it affects

For each ingredient in Immune Lozenges Lemon with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Honey3 drug types · 738 drugs

Phenytoin (Dilantin)

Theoretically, honey might increase levels of phenytoin.
In an animal model, the rate and extent of absorption of phenytoin was increased by honey. This effect has not been reported in humans.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, honey may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
In vitro, honey inhibits platelet aggregation and increases the time to clotting. Furthermore, animal research suggests that feeding mice large doses of honey for 12 days increases bleeding time when compared with no intervention. However, these effects have not been reported in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, honey might decrease levels of drugs metabolized by CYP3A4, but research is conflicting.
Some clinical research shows that honey induces CYP3A4. However, other clinical studies found no effect on CYP3A4 activity. Different honey preparations may have different effects on CYP3A4.

Likelihood Possible Evidence B
Honey full monograph & interactions

Vitamin C13 drug types · 207 drugs

Alkylating Agents

Theoretically, antioxidant effects of vitamin C might reduce the effectiveness of alkylating agents.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Aluminum

Vitamin C can increase the amount of aluminum absorbed from aluminum compounds.
Research in animals and humans shows that vitamin C increases aluminum absorption, theoretically by chelating aluminum and keeping it in solution where it is available for absorption. In people with normal renal function, urinary excretion of aluminum will likely increase, making aluminum retention and toxicity unlikely. Patients with renal failure who take aluminum-containing compounds such as phosphate binders should avoid vitamin C supplements in doses above the recommended dietary allowances.

Likelihood Probable Evidence B
Antitumor Antibiotics

Theoretically, the antioxidant effects of vitamin C might reduce the effectiveness of antitumor antibiotics.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as doxorubicin. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Estrogens

Vitamin C might increase blood levels of estrogens.
Increases in plasma estrogen levels of up to 55% occur under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. Increases in plasma estrogen levels may occur when patients who are deficient in vitamin C take supplements. Monitor these patients for estrogen-related side effects.

Likelihood Probable Evidence B
Fluphenazine (Prolixin)

Theoretically, vitamin C might decrease levels of fluphenazine.
In one patient there was a clinically significant decrease in fluphenazine levels when vitamin C (500 mg twice daily) was started. The mechanism is not known, and there is no further data to confirm this interaction.

Likelihood Possible Evidence D
Indinavir (Crixivan)

Vitamin C can modestly reduce indinavir levels.
One pharmacokinetic study shows that taking vitamin C 1 gram orally once daily along with indinavir 800 mg orally three times daily reduces the area under the concentration-time curve of indinavir by 14%. The mechanism of this interaction is unknown, but it is unlikely to be clinically significant in most patients. The effect of higher doses of vitamin C on indinavir levels is unknown.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Vitamin C can increase levothyroxine absorption.
Two clinical studies in adults with poorly controlled hypothyroidism show that swallowing levothyroxine with a glass of water containing vitamin C 500-1000 mg in solution reduces thyroid stimulating hormone (TSH) levels and increases thyroxine (T4) levels when compared with taking levothyroxine alone. This suggests that vitamin C increases the oral absorption of levothyroxine, possibly due to a reduction in pH.

Likelihood Probable Evidence B
Warfarin (Coumadin)

High-dose vitamin C might reduce the levels and effectiveness of warfarin.
Vitamin C in high doses may cause diarrhea and possibly reduce warfarin absorption. There are reports of two people who took up to 16 grams daily of vitamin C and had a reduction in prothrombin time. Lower doses of 5-10 grams daily can also reduce warfarin absorption. In many cases, this does not seem to be clinically significant. However, a case of warfarin resistance has been reported for a patient who took vitamin C 500 mg twice daily. Cessation of vitamin C supplementation resulted in a rapid increase in international normalized ratio (INR). Tell patients taking warfarin to avoid taking vitamin C in excessively high doses (greater than 10 grams daily). Lower doses may be safe, but the anticoagulation activity of warfarin should be monitored. Patients who are stabilized on warfarin while taking vitamin C should avoid adjusting vitamin C dosage to prevent the possibility of warfarin resistance.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

High-dose vitamin C might slightly prolong the clearance of acetaminophen.
A small pharmacokinetic study in healthy volunteers shows that taking high-dose vitamin C (3 grams) 1.5 hours after taking acetaminophen 1 gram slightly increases the apparent half-life of acetaminophen from around 2.3 hours to 3.1 hours. Ascorbic acid competitively inhibits sulfate conjugation of acetaminophen. However, to compensate, elimination of acetaminophen glucuronide and unconjugated acetaminophen increases. This effect is not likely to be clinically significant.

Likelihood Probable Evidence B
Aspirin

Acidification of the urine by vitamin C might increase aspirin levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction is not clinically significant.

Likelihood Possible Evidence B
Choline Magnesium Trisalicylate (Trilisate)

Acidification of the urine by vitamin C might increase choline magnesium trisalicylate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

Likelihood Possible Evidence B
Niacin

Vitamin C might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as vitamin C, or to the combination. It also is not known whether it will occur in other patient populations.

Likelihood Possible Evidence A
Salsalate (Disalcid)

Acidification of the urine by vitamin C might increase salsalate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams/day vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.

Likelihood Possible Evidence B
Vitamin C full monograph & interactions

Lemon Peel Essential Oil1 drug type · 1 drug

Itraconazole (Sporanox)

Theoretically, taking itraconazole capsules or tablets with a beverage containing lemon might increase the levels and clinical effects of itraconazole.
In one case report, dissolving itraconazole tablets in a small amount of specific beverages containing lemon prior to administration increased the level of itraconazole in a lung transplant patient. In this case, the increased bioavailability was desirable and was likely due to improved tablet dissolution in the acidic beverage.

Immune Lozenges Lemon by Gaia Herbs: Common Questions

Does Immune Lozenges Lemon by Gaia Herbs interact with any medications?
Yes. Based on its ingredients, Immune Lozenges Lemon has a known interaction with 827 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Immune Lozenges Lemon contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I use these lozenges if I'm pregnant?
Honey in this product is likely safe during pregnancy as a food. However, the data advises against high-dose vitamin C in pregnancy — though normal dietary amounts and prenatal vitamins are considered likely safe. Talk to your doctor or pharmacist before taking this product while pregnant, so they can assess the dose and your individual needs.
What are the most common side effects?
From honey, you might experience nausea, stomach pain, or vomiting. From vitamin C at higher doses, abdominal cramps, heartburn, diarrhea, and nausea are most common. From lemon, heartburn and stomach upset can occur. Most people tolerate this lozenge well at normal use.
Does this actually help with cough?
Honey is possibly effective for cough based on clinical evidence, though the evidence isn't definitive. That's the main active ingredient here for cough relief; the vitamin C and lemon peel don't have established evidence for cough specifically.
Is it safe for children?
Honey is generally safe for children over 1 year old. Do not give honey products to infants under 1 year because of the rare risk of botulism. For children over 1, check with your pediatrician about whether this lozenge is appropriate for their age.
Can I breastfeed while taking these lozenges?
Honey eaten by a breastfeeding mother is considered fine as food. Vitamin C at normal amounts is safe during breastfeeding. Talk to your doctor or pharmacist about using this product medicinally while nursing to make sure the dose is appropriate for you and your baby.
Will these lozenges interact with my thyroid medication?
Yes — vitamin C in this product can increase how much levothyroxine (thyroid medication) your body absorbs, which actually improves thyroid control in people with poorly controlled hypothyroidism. However, this interaction means your doctor may need to adjust your dose. Check with them before starting this product.
